Low-temperature synthesis of chemically homogeneous lead zirconate titanate (PZT) powders by a semi-wet method

Abstract

A semi-wet procedure for the synthesis of single-phase Pb(ZrxTi1-x)O3 powders at 600 °C is described. The ultrafine powders so obtained do not exhibit tetragonal/rhombohedral distortions until they are sintered at higher temperatures. The morphotropic phase boundary (MPB) for these powders, which are chemically homogeneous, lies between x=0.52 and 0.53. For x=0.525, the rhombohedral and tetragonal phases coexist. © 1993 Chapman & Hall.
